Specification of Letters Patent.

Patented April 7, 1908.

Application filed July 20, 1906. Serial No. 327,075.

To allcuhom it may concern:

Be it known that I, HARRY L. RICE, of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Channeling.

In making'McKay-sewed shoes, it is customary to for'ma channel in the soles prior to their attachment to the upper, for the reception of the stitches, and then to crowd the leather back to close the chanels.

This invention has for its object to provide a channeling tool which will form an open channel for the leathen forming the sides of the channel in condition to be easily crowded or forced back toclose the channel and cover the stitches.

Tools, of which the following is a specificar Referring to the accompanying drawings,

ness towards its rear end.

Figure 1 represents in perspectwe one form of the invention. Fig. 2 represents the same in front elevation. Fig. 3 represents the same in side elevation. Fig. 4 represents a section on line 44 of Fig. 2.

The tool is formed with any suitable body as at a, which may he clamped or otherwise secured to a holder or carrier (not shown). From the body depends or projects a straight cutter b, which in cross section is triangular or wedge shaped with its front edge shar as at b. Extending laterally from the en of the cutter b are two wings or lateral cutters,

c 0, each having a sharp front cutting edge 0, the edges 6 c c lying in substantially the same plane, and the edges 0 0 being at right angles to the edge I) and all meeting at a common oint. The sir es of the lateral cutters converge rearwardly for clearance as shown in Fig. i, and each of said cutters increases in thick: Although the edges of the cutters c c are at an angle of 90 to the cutter 5, yet the angles (1 (2? merge rearwardly into concave surfaces d.

In operation the cutting edge 6 cuts a slit purpose stated, and leave the 5 ing laterally and at right in the sole at a right angle tothe plane of the sole, and theedges c c undercut the leather in slits substantially parallel with said plane. As the tool and the sole are moved one with relation to the other, the leather lips on the sides of the upright cutter thus formed are thrown upwardly and outwardly by. the curved surfaces (2 to leave the channel open. Thereafter, the stitching being completed, the1 lips may be replaced by any suitable too Having thus explained the natureof the invention, and described a way of construct-' ing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I declare that what I claim is:

1. A channeling tool comprising a body, a straight projecting cutter, and two lateral cutters at the lower end of the straight outter, said cutters having cutting edges meeting at a common point, said lateral cutters decreasing in width rearwardly.

2. A channeling tool comprising a body having at its front edge a straight projecting cutter, and two lateral cutters at the lower end of the straight cutter, said cutters all having sharp edges which form two right angles.

3. A channeling tool comprising a body, a straight. projecting cutter, and two cutters at the lower end of the straight cutter projectangles thereto, said cutters having sharp edges meeting at a common point, the angles formed by the lateral cutters with the straight cutter merging rearwardly into concave surfaces substantially as set forth.

In testimony. whereof I have affixed my signature, in presence of two witnesses.
